The Cemented Material Dam: A New, Environmentally Friendly Type of Dam

Jinsheng Jia, Michel Lino, Feng Jin, Cuiying Zheng

Engineering 2016, Volume 2, Issue 4, Pages 490-497 doi: 10.1016/J.ENG.2016.04.003

Abstract:

The first author proposed the concept of the cemented material dam (CMD) in 2009.for both the dam and the area downstream.The concept covers the cemented sand, gravel, and rock dam (CSGRD), the rockfill concrete (RFC) dam (or the cemented rockfill dam, CRD), and the cemented soil dam (CSD).This paper summarizes the concept and principles of the CMD based on studies and practices in projects

Emerging and Innovative Materials for Hydropower Engineering Applications: Turbines, Bearings, Sealing, Dams and Waterways, and Ocean Power Review

Emanuele Quaranta, Peter Davies

Engineering 2022, Volume 8, Issue 1, Pages 148-158 doi: 10.1016/j.eng.2021.06.025

Abstract:

The hydropower sector is currently experiencing several technological developments. New technologies and sustainable practices are emerging to make hydropower more flexible and eco-friendly. Novel materials have also been recently developed to increase performance, durability, and reliability; however, no systematic discussions can be found in the literature. Therefore, in this paper, novel materials for hydropower applications are presented, and their performance, advantages, and limitations are discussed. For example, composites can reduce the weight of steel equipment by 50% to 80%, polymers and superhydrophobic materials can reduce head losses by 4% to 20%, and novel bearing materials can reduce bearing wear by 6%. These improvements determine higher efficiencies, longer life span, waste reduction, and maintenance needs, although the initial cost of some materials is not yet competitive with respect to the costs of traditional materials. The novel materials are described here based on the following categories: novel materials for turbines, dams and waterways, bearings, seals, and ocean hydropower.
